In May 2019 representatives of the “Sea Eye” system project team of the 715th Research Institute of China Shipbuilding Industry Corporation (hereinafter referred to as the 715) came to the auditorium of the central organ of the League and was awarded the honorary title of the 23rd “Chinese Youth May 4th Medal Collective”.

Zhou Lisheng, the chief designer of the project and director of the 715 Institute, is the backbone of this young team. In the summer of 2014, the "Haiyan" system was in a critical period of comparison. He was "forced" to be hospitalized because of overwork and a high fever. At the coordination meeting, when the project plan was faced with a dilemma, Zhou Lisheng, who pulled out the needle without authorization and slipped out of the hospital, appeared in the meeting place in time. At the meeting, he was sweating, but he still insisted on listening to the failure cause analysis report and reviewing alternative plans.

In the early stage of the project, Chen Tuo, the leader of the overall signal processing team, accidentally fell over tired, and her arm was dislocated and turned out, frightening everyone. At this time, the test ship has already set off. If it returns halfway, the test will inevitably be delayed and the mission cannot be completed on time. Chen Tuo made up her mind that she must not affect the entire project for personal reasons. She endured the pain after the dislocation and insisted that the project team continue the experiment.

From November 20th to 21st 2019, Lei Fanpei went to the 715 Institute for research and guidance. Du Gang accompanied the investigation. Lei Fanpei visited the 715 comprehensive exhibition hall and the key laboratory of sonar technology, inspected the progress of key projects and the test site on the lake, and had a cordial exchange with the officials and staff of the 715.

After listening to relevant reports, Lei Fanpei emphasized that the 715 Institute is a vital force in the construction of marine equipment and a backbone force in the construction of underwater acoustic equipment. "After years of accumulation and development, it has shown vigor and vitality for development. During the strategic opportunity period, we will further focus on the main responsibilities and main business, take the lead, and strive to build a world-class underwater acoustic research institute".

Lei Fanpei requested that the 715 Institute should "earnestly study the spirit of Xi Jinping’s new era of socialism with Chinese characteristics and General Secretary Xi Jinping’s important instructions and instructions to the group company, strengthen the "four consciousnesses", strengthen the "four confidences", and achieve "Two maintenances", take the initiative to act, and provide important support for the comprehensive construction of a modern and powerful country.

"Second, it is necessary to find the gap between the international advanced level and the strategic transformation and development of the navy, adhere to the problem orientation, identify shortcomings, and further improve the technical level and equipment quality of underwater acoustics, and provide solid technical and equipment support for the modernization of the navy. Third, we must further focus on the main responsibilities of the main business, deepen the construction of naval equipment and marine equipment, and work hard on the research and development and mass production of civilian products, so as to strengthen and expand the technology industry. Fourth, we must focus on quality improvement, promote refined management, and use first-class products to serve the building of a first-class navy. Fifth, we must seize development opportunities, plan development based on long-term overall planning, grasp the main direction and supporting conditions and capacity building, strengthen scientific and technological innovation, strengthen joint cooperation, and continuously improve competitiveness. Sixth, we must strengthen the construction of systems and mechanisms, thoroughly explore new paths for the integration of factories and institutes, and the integration of research and production, make good use of incentive policies, and fully mobilize the enthusiasm of cadres and employees.

"Seventh, we must focus on training outstanding young cadres, strengthen the construction of the talent team, and strive to form a cadre and talent team with a reasonable structure and excellent quality. Eighth, we must comprehensively strengthen party building and promote strict governance of the party, implement the "two responsibilities", give full play to the fortress and exemplary role of party branches and party members in overcoming difficulties and catch up with the first-class, and lead all employees to remember their original intentions. Keep the mission in mind and work together to build a world-class underwater acoustic research institute".

The heads of relevant departments of the group company and the leadership of 715 participated in the investigation.
